Classical music fans have every reason to be suspicious of a chamber music group made up of three young and beautiful sisters who wear haute couture dresses, play music by David Bowie and The Doors, and pose for ads for The Gap. Not to worry. The Ahn Trio — pianist Lucia Ahn, violinist Angella Ahn, and cellist Maria Ahn — are Juilliard graduates who have recorded Dvorák and Shostakovich. Their real interest, though, runs to the hard stuff — contemporary music by the likes of Eric Ewazen, Dan Coleman, and John Zorn as well as rock — and they play it all with a zest and enthusiasm that contrasts sharply with the cool approach that the older, more established Kronos Quartet takes to the same material.

They’ll be playing in Grapevine this weekend to raise funds for the various programs sponsored by the Arts Council of Northeast Tarrant County. Their recital includes Ravel’s gem-like Piano Trio in A minor, Michael Nyman’s The Yellow Beach, Kenji Bunch’s adaptation of Katrina Wreede’s work for string quartet Mr. Twitty’s Chair, and Bunch’s own Swing Shift, a John Adams-meets-jazz suite that was composed especially for the trio, to accompany a dance piece by the David Parsons Dance Project. Bass Hall usually snags the cutting-edge acts like these, but this weekend, it’s northeast Tarrant County’s turn.
